2 Claims.

My invention relates to sawn shingles made chiefly from cedar though other woods are used. The quality and grade of shingles are very carefully regulated by rules of certain grading associations so that sawn shingles of a good grade are practically uniform in quality wherever purchased.

It is customary to lay these graded shingles a fixed distance to the weather or having the to lower end exposed for a given amount, 4 5 and 5 inches being the standard exposures varying somewhat with the grade of the shingle.

In laying these shingles on a roof great care must be exercised that the surface shall not be bruised since a bruise on the surface will hold water and despite rot resistance of the woods used they will rot.

Shingles are commonly laid by striking a chalk line on a previous course and laying the succeed- Contractors frequently steal one-quarter to threeeighths inch on each course of shingles by making the exposure greater than standard, which is not apparent from the ground and which results 5 in a below standard roof. One object of my invention is to make this impossible.

Another object of my invention is to speed up the laying of shingles by making the use of the chalk line unnecessary. This also accomplishes 0 another object of making it convenient for one man to lay shingles since manipulation of a chalk line customarily requires two men.

My invention consists broadly in a mark imprinted on both sides of a sawn shingle, in such 5 a manner that the fibre is not bruised or disturbed of a shingle rapidly and will not disturb the fibres of the shingle.

The invention consists in a machine for imprinting the mark thereon, illustrated and described in the accompanying drawings in which,-

Fig. I represents an end view of the intake or feeding end of the machine;

Fig. II is a reference View or view of the 0pposite end of the machine;

Fig. III is a section on the lines 3-3 of Fig. II;

Fig. IV is a top or plan view of the machine as a whole;

' Fig. V is a shingle showing the exposure mark on one side; and

Fig. VI is a projection of the shingle with nu- 60 merals S1 and S2 indicating the location of the exposure mark.

The machine consists essentially of frames, 9 and 9a, shown to be spaced apart by distance rods, 10. 10a, 11, and 11a, which are adjustable as 65 to length by manipulating nuts such as 12 and 12a.

Mounted in suitable bearings are the vertical shafts 13, 14, 15, and 16. Elements 13 and 14 have miter gears 16 and 17 meshing with miter 7Q gears 18 and 19 upon the shaft 20 which receives power from the pulley 21, driven by a source not shown, the pulley, 21, being mounted upon the shaft, 200., upon which is mounted pulley 23, opcrating belt 22a, and delivering power to pulley 22 on shaft 20 at the opposite end of the machine and upon which are mounted the bevel pinions, l8 and 19, heretofore described, the transmission being taken in this direction and the delivery end of the machine receiving power through the belts 13c and lie to permit the delivery end of the machine to be movable to hold shingles firmly while being marked.

Mounted between the vertical shafts 13 and 14, 15 and 16, are the pulleys 22 and 23 carrying the belt, 22c, preferably made of canvas rubber covered and of the type known as rubber belt.

Mounted upon the vertical shafts 13, 14, 15 and 16, properly spaced, are pulleys 13a, 13b, 14a, and 14b, 15a, and 15b, 16a, and 16b, also carrying belts of the same type; and it will be noted that the shafts l3 and 14 are spaced further apart than the shafts 15 and 16 so that the space between these belts indicated by the letter B converges.

This machine being arranged for end feed, the shingles as represented by the dotted outline S in Fig. I are set in with the butt ends of them resting upon the belt 22a and reaching upward between the pulleys 13a, 13b, l iaand 14b which carry belts 13c, 14c, 14d, and 14a and all of the several belts are arranged to run at the same lineal speed, which in hand fed machines will be as fast as a trained operative can place the shingles thereon.

The shaft 15 is mounted movably in a connecting rod 24 and 25 at the top and bottom respectively and bearing on the free end of this connecting rod is a spring 26 at the top and 27 at the bottom tending to hold the pulley and the carried belt yieldingly against its companion belt or against a shingle that may be carried into the machine.

Adjustably mounted upon the shafts 15 and 16 are sheaves 28 and 29 having V grooves 28a and 29a within which are contained rubber belts 30 and 31 of square cross section stretchable to occupy the V grooves and remain firmly therein, and which may be changed to present four printing edges at difierent times as wear makes it necessary.

An inking device represented by a disc 32 runs in contact with the rubber belts 30 and 31 being held yieldingly against the belts by the spring 33 which tends to move the mounting shaft 34; in

the proper direction. 7

The lower part of the disc 32 runs in a container 35 containing thin printers ink or other suitable coloring matter for marking the shingles. The sheaves 28 and 29 being adjustable may of course be moved vertically to place the exposure mark on the shingle at a desirable distance from the butt and on both sides thereof simultaneously and it may be certain that every shingle passing through the machine will have a mark on both sides of it at a predetermined distance from the end constituting the exposure mark described as desirable in the preamble.

It is of course obvious that the mechanical equivalent of this machine may be constructed without strictly following the illustrations and description. I therefore desire to limit myself only by the following claims:

I claim:

1. In a machine for printing an exposure mark on a shingle, a horizontal conveyor belt, a plurality of vertical belts for maintaining the shingle in vertical position and a pair of inked rollers for printing an exposure mark on both sides of
